Optical regeneration is a key factor in the ever faster telecom networks. The goal of this reserach topic is the development of a very fast 2R-regenerator based on the low carrier lifetime in the presence of high optical power. The high optical power considered is that of a laser signal that is created in an interferometric cavity. This interferometric cavity will also be used as a plain interferometer for injected signals whilst maintaining the laser signal. Due to the presence of the laser signal and the following low carrier lifetime a fast response to injected signals could be possible. Constructive interference for the '1' level and destructive intereference for the '0' level is desired to obtain 2R-regeneration.
